2 APK  A farmer buys 2.5 km of wire for fencing. He uses 850m in one field... …and 1.25km in another. How much wire does he have left?

3 NEW INFORMATION How do you work out the answer to a word problem? Read the question. Convert the units in the question so that all the units are the same, if possible. Decide what operation(s) to use. Write down the calculation(s) you are going to do. Use brackets if you need to. Work out the approximate answer. Decide how you will work out the calculation. Ask: Can I do it in my head? Do the calculation and interpret the answer. Include any units (e.g. km). Ask: Does the answer make sense?

4 In Interactive Notebook Year 5s and 6s: 1.Farmer Dom’s sheep are escaping out of his field, he needs to put a fence around it. a. The length of the field is 24 metres, the width is 10 metres How much wooden fencing does farmer Dom need to purchase to go around his field. b. Farmer Dom notices that there is very little grass on his field, so he decides to resurface it with new grass. So farmer Dom doesn’t get too little grass he decides to measure the area of the field, however he does not know how to do this, can you help him? c. The grass comes in strips of 5 metres long and 2 metres wide. How many strips does farmer Dom need to purchase in order to cover his field sufficiently. APPLICATION (PRACTICE)

5 In Interactive Notebook Year 5s and 6s: 2.Amardeep and Rajvi have just bought a new house, they would like to carpet two rooms in their house. a.

Using centimetres work how much green border paper Sarah needs? APPLICATION (PRACTICE)
